SLIDING-DOOR HANGER.

Specification of Letters Patent.

Patented Oct. 15,1912.

Application filed December 31, 1910. Serial No. 600,273.

To all whom it may concern Be it known that I, O'r'ro W. DOLPI-I, a citizen of the United States of America, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented a certain new and useful Improvement in Sliding-Door Hangers, of which the following is a specification.

This invention relates to slidingdoor hangers and especially to those doors that are adapted to slide over a bar or track and used in the door-ways of vehicles, elevators, cars and buildings.

The object of the invention is to provide compensating or space take-up spring-controlled rollers that are adapted to closely engage the upper and lower edges of the horizontal bar or track on which the door is hung, whereby an anti-rattling hanger device is efiected that obviates any undue and annoying rumble or noise and one that sustains the door in the desired perpendicular position in its reciprocal movements for the closing and opening of the door-Way.

The novel features of the invention will be fully hereinafter described and particularly pointed out in the claim.

In the accompanying sheet of drawings, Figure 1 is a fragmentary elevation showing the inner face of a door and an anti-rattling hanger device embodying my invention herein in its preferred form, and Fig. 2 is a sectional elevation taken on the dotted line a, a, of Fig. 1.

In said views, 1 indicates a door, 2 the base of the door-way over which the door is suspended and moves, and 3 the vertical or perpendicular part of the structure in which the door-way is made and to which the door is connected for reciprocal movement across said door-way. These parts may be those ordinarily present in a vehicle, a freight or passenger elevator, a freight or passenger car, or a building structure, wherever a sliding-door is desired.

4 indicates a horizontal bar forming a suitable track over which the door, through the agency of its hanger devices, is adapted to slide. This bar is supported by means of brackets 5 that are secured to the upright part 3 of the structure, above the entrance or door-way thereof.

6 indicates a vertical plate or bar having a lateral arm 7 extending centrally therefrom. Two or more of these plates 6 are secured, at suitable distances apart, to the up per part of the door, with their vertical members extending beyond the upper edge of the door.

8, 8 indicate a pair of lateral, vertically alined tubular bearings extending from the upper extension of each of the bars 6, and 9 indicates the broad flanged or headed pins that are mounted in said bearings and riveted at 10 on the face of the said bars 6. 11 indicates flanged rollers mounted on said tubular bearings and adapted to engage the upper and lower edges of the horizontal bar 4, as best seen in Fig. 2. A spiral-spring 12 is mounted on each of the bearings 8, intervening the adjacent roller and broad head of said pin, in connection with each of the roller devices. The expansion of said spring serves to take up any looseness in the hanger device and thereby prevents rattling and noise, and is practically a space and wear compensating device forming the most essential feature of my invention herein. A suitable space 12 is allowed between the inner face of the rollers and the adjacent face of the bar 6 so that said rollers shall ride freely over the horizontal bar 4 and not contact with the said bar 6.

I claim In an anti-rattling sliding-door hanger device, a vertical suspensionbar, lateral tubular bearings duly spaced apart at the upper projecting end of said bar, broad headed or flanged pins mounted in said tubular bearings, flanged rollers mounted on said tubular bearings, and compensating take-up spiral-springs also mounted on said tubularbearings intermediate said rollers and the broad heads or flanges of the pins.
